IMPROVBD GARBURETTING-APPARATUS.

TO ALL WHOM IT MAY CONCERN:

Be it known that we, WILLIAM THOMPSON and J. E. HALL, of Cleveland, in thc county of Cuyahoga, and

State of Ohio, have invented certain new and useful Improvements in a Oa-rburctting-Apparatus; and we do.

hereby-declare that the following is a full and complete description of the saine, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is a side view of the apparatus.

Figure 2- is a view ot' the inside.

Figure 3 is a'vertical transverse section.

-The other figures are detached sections, to which reference will be made.

Like letters of reference refer to like parts in the several views.

A, tig. 1, is the shell or case of the apparatus, which may be constructed of tin or galvanized sheet iron,

and of any required capacity. Within this shell is a lining of perforated tin, B, iig. 3, the diameter of which` is considerably less than the case, thus leaving a space all around betweenlthe tin, andwhich space is partitioned ofi' into sections corresponding in number to the number of dependent spouts or sleeves C, each sleeve having itsseparate section. These several spouts and sections vare filled with cotton, D, or any other suitable occulent material, the purpose of which will be hereafter shown. E, Figure 7, is a circhlar float, the radial arms F,- gs. 2 and 3, of which reach out towards the centre of the case, which are then turned upward and united at the top, and connected to a wooden standard or guide, G, enclosed within the induction-pipe H, and in which it rises upward and downward as the float may affect it, as will hereafter be described. From the end of this standard or guide projects a point, I, on which is the agitator J, Figure 5, which consists of an outer shell or case, K,ig. 3. Within this shell is an annular chamber, L, in the upper end of which are arranged the fan-like wings M, Figure 6, and between the walls of the chamber and case arc projectedthe spiral wings N, also indi cated by dotted lines in iig. 5, the purpose of which will hereafter be shown. Projectingfrom the sides of the shell, and communicating with the space between the walls of the shell and chamber, are tubular arms O, pro'- vided with dependent ears P. This agitator, when suspended upon the float, as shown in tlg. 3, is then covered with a double top'ot` perforated tin, Q, fig. 4, the space between which is filled with cotton-wicking or other like material, as is the space between the case and perforated lining B, thus surrounding the agitator with aperfo rated top and lining, also with a material ot a fibrous texture. 3 Projecting from thetop of the agitator, and penetrating through the cover Q into the cone R, is a standard, S,- the purpose ot' which will presently be shown;

Having thus indicated the construction and arrangement ofthe several parts of the apparatus, the pracftical application and operation of the same are as follows: The carburetter is placed in any convenient out-of? the-way place, between the gas-meter and burners, and which is connected to the meter by the pipe H, through which the gas is inducted into the apparatus. A certain quantity of gasoline, or any Huid highlyT charged with carbon, is poured into the apparatlis through the supply-pipe T, g.1, until the iloat rises up to about the height of the dotted line a, fig. 3, which will beascertained by the point of the standard' 'S, as seen through the eye-glass U, fig. 1, an index being arranged to indicate the quantity in the machine. As above observed, the gas is inducted into the machine through the pipe H,.to the top of the chambervL, through which it pass's, thence down between the walls of the chamber and shell, and out at the bottom through the tubular arms D; thence out of the sides of which, through the ports 6, Ainto the fluid, and from which it escapes to the outside of the agitator into the'space surrounding-itabove the Huid. From this `space the gas escapes to the top of the apparatus, by being compelled rst topass through the perforated lining and top, as well as through the filling between them, and from which it passes through the eduction-pipe to the burners. By this course it will be evident that the gas, as it leaves the apparatus, must be highly charged with carbon, first 'by passingfthrough the duid, and secondly 'by passing through the lining und cotton, which latter, by theaction of capillary attra@ tion, has become fully saturated with the fluid, and thus giving to thetiuid a very large evaporating-surface,

whereby it is brought-more immediately and largely in combination with the gas, and thus carburetting the same in the most complete manner. In order tofacilitate the evaporation otthe Huid, and thereby produce a more immediate and intimatemingling of thc gas and Huid, or the vapors of the Huid, the iioat above referred to, as it is brought up,is made to rotate bythe pressure exerted upon the fan-like wings M and the spiral wings N as the gas is passing through and over them; so also, as the gas escapes from vthe tubular arms O through the ports b, the reaction of the flowing gas contributesA to the rotating of the agitator, and thus, by the direct and reactive energy of the gas, the agitator is kept revolving and agitating the fluid by means of thc dependent ears P, and the evaporation therefore largely increased, and the purpose of'carburetting the gas 'more-fully and speedily eected. y

What we claim as our improvement, and desire to secure by Letters Patent, is-

1. The agitator J, constructed vwith an annular chamber, L, wings M and N, and tubular arms O, in the manner and for the purpose substantially as set forth. v

2. Perforated lining B, top Q, spouts or sleeves C, and cotton,.D, or its equivalent, as arranged, in combination with the oat E and agitator J, in the manner and for thc purpose substantially as described.

3. The ioat E, agitator J, constructed as described, in combination with a Carburettor, in the manner and for the purpose substantially as described.

4.4 The herein-described apparatus, provided with a float and a revolving agitator, constructed as described, whereby the carburetting-luid is agitated for-the purpose of largely increasing its evaporation or elimination,

substantially Aas and for the purpose set forth.
